Abstract：For a long time, the rice stem borers are main insect pest in rice. With the change of rice cultivation and climate change, the populations of the rice stem borers increase gradually, which damage the rice yield more and more seriously in recent years. Therefore, it’s very meaningful for the integrated management of the rice stem borers to investigate the dynamics scientifically and forecast accurately their trends. According to biological characteristics of Sesamia inferens (Walker), Chilo suppressalis (Walker), Scirpophaga incertulas (Walker), the surveying methods of these borers in the field were summarized. And three forecasting methods of occurrence stage were demonstrated. Moreover, some attentions during the survey were discussed. In conclusion, these methods and technologies will provide a strong foundation for the integrated management of the rice stem borers.
